It adds 13 new spells, 1 new Sorc bloodline, 1 new Wiz speciality and Ice Domain. Along with a new feat Cold Focus (add +2 to DC of cold spells) and a new monster template, Arctic.

The spells are mostly interesting and seem balanced. Several of them are based losselly on existing spells. I would have liked to have seen a few more inventive new spells, that really fit the concept*. If it had, had more spells like that i would have given it 5 stars likely. I do hope they do a follow up book to this. Perhaps a elements book that adds in more spells for all 4 elements including a lot more ice spells.

*Example of what I mean. they have create ice a cantrip that makes a 5 ft sheet of ice. But I would have liked to have seen this expanded and the level increased.
